Subject: about selftests/netfilter test related issue

hello
i think the script nft_nat.sh  is assuming devices eth0 and eth1
which may not be the case always. my suggestion is why not give the needed
network devices as arguments to the script. iam showing related
command line sessions below and error related file is attached.
